Deflection resistant tent

ABSTRACT

A deflection resistant tent is set forth. The framework of this tent comprises an upper nest, an lower nest, a plurality of upper rib strips, lower rib strips, auxiliary rib strips, adjustable collars, articulation members, and spring stays. The articulation member is composed of an upper sleeve, a retainer, a torque member, and a lower sleeve. With this structure, the elastic force of the spring stay controls the retainer to make clockwise rotation until it is stopped by a blocking face so as to settle the lower sleeve at a desire position that can prevent the unexpected collapsing of the tent by a sudden external force or a violent wind blow.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a deflection resistant tent, inparticular to a tent which can prevent an unexpected collapsing due to asudden external violent force by means of the alleviative function ofspring stays provided between the upper and lower rib strips.

2. Description of the Prior Art

A conventional foldable tent used to contain an inner and an outercanopies. The inner one is for shading the living space, while the outerone is for keeping the sunlight and rainfall away from the inner space.As the canopy is two layerd, it really has an excellent effect of heatisolation and ventilation as well so that it is well suitable for usingin picnic.

However, according to the inventor's experience in using above describedtent for years. It has the following inherent shortcomings:

1. In a conventional tent, a joint is intercalated between each upperrib strip and lower rib strip for folding the two rib strips inwardlywith each other. It is due to the fact that the articulation motion ofthe joint is not provided with a retaining effect. A sudden strong windblow or other external force might cause an unexpected collapsing of thetent and might hurt the users inside.

2. When folding the tent, the operation requires the user to crouchdown.

For these shortcomings noticeable on the prior art, an improvement isseriously required. The invention has endeavored for years by continuousresearch and experimentation trying to find out the remedy to rectifythe inherent shortcomings of the conventional tent described above, andat last has succeeded in realizing the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

For fuller understanding the features and advantages of the presentinvention, please refer to the following detailed description of thepreferred embodiments in conjunction with the drawings.

Referring to FIG. 1 through FIG. 4. the framework of the deflectionresistant tent comprises an upper nest 1, a lower nest 2, a plurality ofupper rib strip 3, lower rib strips 4, auxiliary rib strips 5,adjustable collars 6, articulation members 7, and spring stays 8,covered with a canopy 9. The amount of components from 3 to 8 are thesame.

The lower nest 2 is provided under the upper nest 1.

One end of each upper rib strip 3 is inserted and hinged to the edge ofthe upper nest 1, while the other end thereof is stretched downwards.

Each adjustable collar 6 with a holder 61 is fitted to the correspondingupper rib strip 3 at a proper position.

Each auxiliary rib strip 5 is hinged to the edge of the lower nest 2with its one end, and the other end thereof is attached to thecorresponding adjustable collar 6.

Each articulation member 7 is composed of an upper sleeve 71 and a lowersleeve 72. The upper sleeve 71 accepts insertion of the correspondingupper rib strip 3. A mouth 711 with a via hole 712 at its inner side isformed at the lower end of the upper sleeve 71. A retainer 74 isshackled in the mouth 711 and exposed out of the via hole 712. Theretainer 74 has a drilled hole 741 at its one end and an eyelet 742formed at its center. A torque member 75 is provided for controllingclockwise rotating force of the retainer 74. The lower sleeve 72 forinsertion of the top end of the lower rib strip 4 has a hinge joint 73at its upper portion to hinge to the mouth 711. The upper edge of thehinge joint 73 is formed into a blocking face 731 occupying just on therotating way of the retainer 74 so as to limit movement of the lowersleeve 72. Two set pins 76 are respectively passing through the eyelet742 of the retainer 74 and the hinge hole of the lower sleeve 72 suchthat the retainer 74 and the lower sleeve 72 are respectively hinged tothe mouth 711 formed with the upper sleeve 71. A passing hole 751corresponding to the eyelet 742 formed at the center of the torquemember 75 accepts one of the set pins 76 to penetrate through so as tosettle the torque member 75.

Each lower rib strip 4 is inserted into the lower sleeve 72 of thearticulation member 7.

Each spring stay 8 is fastened between the holder 61 of the adjustablecollar 6 and the via hole 712 formed at the inner side of the retainer74 so as to sustain retainer 74.

For understanding how to pitch and fold the deflection resistant tent ofthe present invention, please refer to FIG. 5 through 8 in conjunctionwith FIGS. 2 and 4. When the tent is pitched, the retainer 74 providedin the articulation member 7 rotates clockwise until reaches a positionin balance with the pulling force of the spring stay 8 such that theretainer 74 is confined by the blocking face 731 of the hinge joint 73thereby the lower sleeve 72 can be set at the position not toautomatically fold by an unexpected external force such as a violentwind blow or tampering with by someone. In the case the user wants tostrike the tent, by pulling downwards the spring stay 8, the retainer 74will rotate in the counter clockwise direction due to losing thesustaining force of the spring stay 8 that in turn causes the lowersleeve 72 to be liverated thereby folding all of the lower rib strips 4inserted in it.

A second embodiment of the present invention is shown in FIG. 9 whereinthe deflection resistant tent of the present invention is applicable asa pet tent (a). It can be clearly seen that a gate 91 is formed on acanopy 9.
